Morose, forlorn, or just so darn depressed?

If I look forlorn/morose/depressed enough, will she call?

In missing my sister Golden Hair, newly off to college, I attempted to determine which word most nearly described my state of mind. In my last post on this topic, I used the word forlorn. But then it occurred to me: perhaps I actually am morose.

Upon consulting my dictionary, I find that morose means sullen and ill-tempered. Me? Never!
Depressed? "(of a person) In a state of unhappiness or despondency." Hmm. The dictionary does not include (of a dog), even a very smart one like me. So, I believe that my instinct to use forlorn was correct. Definition: pitifully sad and abandoned or lonely.

Ouch. It hurts.
